The natural process, as the oldest method of coffee processing, can be traced back to the method used by Arabs in the 11th century. This natural drying technique requires no large amount of water and is low in cost, making it widely popular in water-scarce regions. However, the natural process also faces challenges such as contamination by impurities, uneven drying, and mold and rot. This article will break down the four steps of the natural process in detail—removing floating beans, sun drying, observation, and removing the husk—and analyze its positive and negative effects on coffee bean quality. At the same time, we will also explore how the natural process amplifies the coffee's own flavors, bringing a rich body and sweetness, and include Front Street Coffee's pour-over brewing suggestions to help enthusiasts better experience the charm of naturally processed beans.

Located in Hafursa Village, about eight kilometers west of Yirgacheffe town, it sits on slopes between 1,900 and 2,200 meters above sea level. The local processing station has 12 standard fermentation tanks and more than 160 coded drying bed frames, allowing precise tracking of processing progress. High-altitude berries, after washing, present a distinct lemon note, bright and high-pitched with a delicate texture. However, traditional African beds dry too quickly under bright sun and ventilation, which is actually unfavorable for flavor development. This article explores in depth the agronomic principles of the semi-shaded slow drying method and how it extends the drying period to 16–30 days, thereby preserving more complete contents and bringing a completely different flavor and aftertaste experience. Front Street Coffee recommends this Hafursa slow-dried washed G1, which is worth savoring. [more…]
